Selective fetal growth restriction (sFGR) is a major cause of perinatal morbidity and mortality in monochorionic diamniotic (MCDA) twin pregnancies. Current management relies on umbilical artery Doppler patterns in the smaller twin. These patterns are, however, inconsistent and do not represent a reliable severity scale, complicating clinical decision-making and parental counselling. This study aims to improve risk stratification by identifying predictors of adverse outcomes, while also evaluating the pathophysiology and multi-organ impact of sFGR in early childhood.

This is a prospective, international, multicentre cohort study conducted in six tertiary fetal medicine centres with expertise in complicated twin pregnancies. Recruitment began in March 2023 and will continue until December 2026, targeting 274 MCDA twin pairs with complete follow-up to develop a prediction model for adverse perinatal outcomes in sFGR at the time of diagnosis. Standardised data collection includes serial ultrasound examinations, advanced fetal imaging (cardiac, cerebral and 3D volumetric), fetal brain MRI and detailed placental phenotyping. Maternal and parental well-being are assessed during pregnancy and after birth. Neurodevelopmental outcome is evaluated up to 2 years after birth using validated tools. The statistical analysis plan includes predictive modelling with internal validation.

The study has been approved by the ethical review boards of all participating centres. Findings will be disseminated through peer-reviewed publications, international conferences and engagement with clinical guideline committees.

This paper aims to describe the development of an inventory of chronic ambulatory care sensitive conditions (ACSCs) relevant to the Malaysian context and identify potentially preventable hospitalisations in the Malaysian Ministry of Health (MOH) facilities based on the developed list.

Consultative panel discussion, multi-panel modified Delphi and secondary health data analysis.

Setting: Malaysian MOH healthcare facilities.

42 experts from the family medicine and internal medicine specialties (modified Delphi), and 2022 inpatient data from MOH hospitals (secondary health data analysis).

A list of chronic ACSCs tailored to the Malaysian context and the proportion of potentially preventable hospitalisation in MOH hospitals.

10 conditions were identified as chronic ACSCs for Malaysia, namely angina, asthma, chronic kidney disease, convulsions and epilepsy, chronic obstructive pulmonary disease, diabetes mellitus, heart failure, hypertension, iron deficiency anaemia and ischaemic heart disease. In 2022, these conditions accounted for 8.6% of potentially preventable hospitalisations among the total hospitalisations in MOH hospitals.

This study provides a base list of chronic ACSCs tailored to the Malaysian context, which enables monitoring of potentially preventable hospitalisations due to chronic conditions. The findings underscore a proportion of hospital admissions that could potentially be avoided through interventions that enhance outpatient care. The conditions identified as ambulatory care sensitive provide specific targets for policy action and resource allocation to optimise outpatient health services and thus reduce the burden of hospitalisations in the country.

There is an absence of real-world evidence, especially from low- and middle-income countries (LMICs), on the implementation successes and challenges of COVID-19 Test and Treat (T&T) programmes. In 2022, nirmatrelvir/ritonavir was provided as standard of care for mild to moderate COVID-19 treatment in eight LMICs (Ghana, Kenya, Laos, Malawi, Nigeria, Rwanda, Uganda and Zambia). This manuscript describes a research protocol to study novel drug introduction during the COVID-19 health emergency, with implications and learnings for future pandemic preparedness. The goal of the study is to provide simultaneous programme learnings and improvements with programme rollout, to fill a gap in real-world implementation data on T&T programmes of oral antiviral treatment for COVID-19 and inform programme implementation and scale-up in other LMICs.

This multiple methods implementation research study is divided into three components to address key operational research objectives: (1) programme learnings, monitoring and evaluation; (2) patient-level programme impact; and (3) key stakeholder perspectives. Data collection will occur for a minimum of 6 months in each country up to the end of grant. Quantitative data will be analysed using descriptive statistics for each country and then aggregated across the programme countries. Stakeholder perspectives will be examined using the Consolidated Framework for Implementation Research implementation science framework and semistructured interviews.

This study was approved by the Duke University Institutional Review Board (Pro00111388). The study was also approved by the local institutional review boards in each country participating in individual-level data collection (objectives 2 and 3): Ghana, Malawi, Rwanda, Nigeria and Zambia. The study’s findings will be published in peer-reviewed journals and disseminated through dialogue events, national and international conferences and through social media.

Child malnutrition remains a pressing public health challenge in sub-Saharan Africa (SSA), where approximately 148 million children are stunted and 45 million are wasted. Although often conceptualised as a persistent condition, evidence indicates that malnutrition among children under 5 years frequently follows seasonal patterns shaped by agricultural cycles, climatic variability and socioeconomic conditions. Current interventions have paid limited attention to the food system dynamics that underpin these fluctuations. Adopting a system perspective, this scoping review will synthesise existing evidence on the food system determinants of seasonal malnutrition in children under 5 years in SSA.

The review will be conducted in accordance with the Joanna Briggs Institute methodological framework for scoping reviews and reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses - Extension for Scoping Reviews (PRISMA-ScR) guidelines. A comprehensive search will be undertaken across electronic databases (Google Scholar, ProQuest Central, PubMed, Scopus and African Index Medicus) for literature published from 2015 onwards. Grey literature will also be sought from institutional repositories of the WHO, United Nations Children’s Fund, Food and Agriculture Organization and World Food Programme. Screening of titles, abstracts and full texts will be performed independently by two reviewers using predefined eligibility criteria. Data extraction will capture study characteristics and food system determinants of seasonal malnutrition at micro, meso and macro levels. The Food Insecurity and Vulnerability Information and Mapping Systems framework will guide the analysis and synthesis.

As this review involves analysis of previously published data, ethical approval is not required. Findings will be disseminated through a peer-reviewed publication and social media engagements. Results will inform the development of integrated system-based approaches to address seasonal malnutrition in children under five in SSA. The full study protocol, datasets and supplementary forms will be published in an open-access repository in compliance with the Findability, Accessibility, Interoperability and Reuse principles.

The emergency department (ED) often serves as a crucial pathway for cancer diagnosis. However, little is known about the management of patients with new suspected cancer diagnoses in the ED. The objective of this study was to explore emergency physicians’ experiences in managing patients with a newly suspected cancer diagnosis in the ED.

Between January and April 2024, we conducted a qualitative descriptive study. Interviews were conducted by trained research personnel using a semistructured interview guide. Interviews were conducted until thematic saturation was achieved. The interview transcripts were coded and thematic analysis was used to uncover key themes.

Emergency physicians practising in Ontario, Canada.

20 emergency physicians were interviewed. Four themes around the management of patients with new suspected cancer diagnoses in the ED were identified: (1) healthcare system-level factors that impact suspected cancer diagnosis through the ED, (2) institutional and provider-level challenges associated with managing patients with a suspected cancer diagnosis in the ED, (3) patient-level characteristics and experiences of receiving a cancer diagnosis in the ED and (4) the need for care coordination for patients with suspected cancer in the ED.

Physicians experienced several unique challenges in managing patients with a suspected cancer diagnosis in the ED. Overall, the findings of this study suggest these challenges often make the ED a difficult environment in which to deliver a suspected cancer diagnosis.

Postoperative pulmonary complications (PPCs) represent a significant cause of postoperative morbidity and even mortality. However, there is a lack of consensus regarding this composite endpoint, the definition of the individual components, classification and optimal outcome measures. This study aims to refine the PPCs composite framework by evaluating its construct validity, assessing the necessity and risks of a composite measure and exploring the feasibility of differentiating severity categories.

A Delphi consensus process will be conducted, engaging an international multidisciplinary group of 30–40 panellists, including clinicians, researchers, patients, public representatives and health economists. Through iterative rounds, the study will seek agreement on the individual components of the PPCs composite. Additionally, consensus will establish a framework for a composite outcome measure based on a standardised severity classification, appropriate timeframes and weighted grading of PPCs.

Consensus, defined by ≥75% concurrence in multiple choice questions or on Likert–scale statements, will be evaluated from round 2 onwards. Delphi rounds will be continued until all statements have reached stability of responses evaluated by ² tests or the Kruskal-Wallis test.

The study will be conducted in strict compliance with the principles of the Declaration of Helsinki and will adhere to ACCORD guidance for reporting. Ethics approval has been obtained for this study from the University of Wolverhampton, UK (SOABE/202425/staff/3). Informed consent will be obtained from all panellists before the commencement of the Delphi process. The results of the study will be published in a peer–reviewed journal with the authorship assigned in accordance with ICMJE requirements.

To evaluate inhaler sustainability in asthma and Chronic Obstructive Pulmomary Disease (COPD) by analysing how inhaler design typology, prescribing and usage patterns, disposal and recycling practices influence human health and environmental outcomes, using a People-Process-Product (PPP) framework to identify actionable opportunities for improvement.

A systematic review was conducted in May 2024, with reporting structured around the PPP framework using narrative synthesis.

MEDLINE, Scopus, Cochrane Library and relevant grey literature were searched for publications over the period from April 2014 to April 2024.

Studies were included if published between 2014 and 2024, involved patients with asthma or COPD and healthcare professionals and specifically examined aspects of inhaler sustainability, including patient behaviours, healthcare provider prescribing practices and environmental impacts.

Two independent reviewers screened and extracted data from 63 studies. Due to diverse methodologies, quality assessment focused on research design robustness, completeness of outcome reporting and potential biases. Findings were synthesised narratively to address each research question using the PPP framework.

33% of included studies focused on two or more domains of the PPP framework as both primary and/or secondary outcomes. Studies mapped to the ‘People’ domain (n=34) showed limited awareness among patients and clinicians regarding the environmental impact of inhaler prescription patterns, use patterns and disposal methods, with over 75% of patients discarding inhalers in household waste. In the ‘Process’ domain (n=11), switching from pressurised metered-dose inhalers (pMDIs) to dry powder inhalers (DPIs) or soft mist inhalers (SMIs) was associated with improved inhaler adherence and asthma control, though uptake of new inhalers was influenced by patients’ prior experience, competence, proficiency and perceived usability. The ‘Product’ domain (n=41) showed that DPIs and SMIs consistently had lower carbon footprints than pMDIs, with short-acting beta-agonists (SABAs) pMDIs having the highest emissions due to prescription, use patterns and disposal.

Improving patient education on sustainable inhaler use and disposal and providing healthcare professionals with focused training on low-carbon prescribing are critical steps towards achieving significant clinical benefits and supporting environmental sustainability in asthma and COPD management.
